Application filed September 3, 1913. Serial No. 787,944.

To all 'wit-0m t may concern Be it known that we, ALBERT JUGKER, a citizen of the Republic of Switzerland, and 'I1-monos Hmirnn, a subject of the Emperor of Germany, residing both at Kreuzlingen, Switzerland, have invented new and useful Improvements in Tensioning-Frames for Fabric to be Embroidered and the like; and we do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

This invention relates to improvements in tensioning frames for fabric to be embroidered and the like.

The object of this invention is to provide a frame of this kind, in which a rigid inner part and an outer part consisting of a plurality of separate side members connected together by means of springs are held together by means of the opposite sides of these two parts being beveled in the form of steps and working into each other, and in which the fabric is tensioned in all directions and pressed between these two frame parts working together.

Two modes of carrying the invention into effect are shown by way of example on the accompanying drawings in which Figure l shows a plan View of one kind of frame constructed according to this invention, Fig. 2 is a section on the line A-B of Fig. l, showing the different parts of the frame in their operative position, Fig. 3 is a section on the same line, showing the inner and outer frame parts out of engagement one with another, Fig. 4t shows a plan view of the second construction according to this invention, Fig. 5 shows a section on the line C-D of Fig. e and Fig. 6 shows a side view of Fig. il.

rl`he frame illustrated in Figs. 1-3 has a rigid, rectangular inner part l provided with outer sides 2 beveled in the form of steps. 3 are separate side members forming the outer frame part. These members 3 possess inner sides 4; also beveled in the form of steps and corresponding to the sides 2. The side members 3 of the outer frame part are connected together by means of plate springs 5, 6, these springs being fixed to the sideemembers 3 by means of screws 7. The

action of the plate springs 5, 6.

spring` plates 6 are fixed to the longer side members 3 by means of only one screw, so that one of the shorter side-members 3 connected to the plate spring 6 is capable of being turned out of the plane, in which are situated the other side members 3 (see dotted lines in Fig. 2). ilhen the outer and inner frame parts are in their operative position, the sides 2 and e beveled in the form of steps work into each other, so that the inner frame part 1 situated in the same plane as the outer frame part 3 is held by the latter in the proper position. After the above-mentioned shorter side member 3 has been swung out of the plane of the frame, the inner frame part l may be easily disconnected from the outer frame part 3.

If a fabric piece t (Fig. 3) has to be ten-A sioned in the frame, said piece is put, for instance, upon the outer frame part, which is in the position shown in Fig. 3. Heren upon the inner frame part l is put upon the outer frame part, the side members 3 of which are kept together owing to the A pressure acting in the direction of the arrow 8 is then exerted upon the outer frame part, so that its beveled sides engage the beveled sides of the inner frame part l. This causes the fabric to be tensioned or stretched in all directions and the fabric is then tightly held between the inner and outer frame parts l and 3. It is evident that the fabric could also be put upon the inner frame part, in which case it would be necessary to put the outer frame part upon the fabric. For the purpose of loosening the fabric a, which has been embroidered the shorter side member 3 capable of being rotated is swung out of the plane of the frame, whereupon the inner frame part l may be lifted out of the outer frame part and the fabric taken off the frame.

The frame illustrated in Figs. e6 is also of rectangular form and the two longer side members 9 of its outer frame part are formed by plate springs having along the opposite sides of the inner frame part l a proiile corresponding to that of the outer side 2 beveled in the rorm of steps of the inner frame part l. Each end of the plate springs 9 is pivotally connected by means of a screw l0 to a shorter side member 1l of the outer frame part, said springs 9 pressing in their operative position the side members 1l, the inner sides l2 of which are beveled in the form of steps in the same manner as the outer sides 2 of the inner part l, against the latter. To tension and loosen the fabric in a frame of this kind the same operations may be carried out as those described in connection with the first kind of frame. This arrangement, according to which the plate springs form directly parts .of the outer frame part, has the advantage, that the space between two such frames, which may be put for instance in an embroidery machine, is greater than in the case where two frames of the iii-st described kind are used, since no screw heads have to be provided on the longer frame sides and the side members of the outer frame part formed by the plate springs 9 are thinner 'than the separate side members 3 of the outer frame part of the frame shown in Figs. 1 3. Such an enlargement of the space between two frames is, however, very valuable for the storing up of the fabric, which is not tensioned in the frame. It is evident t-hat the frame could also have more than four corners.

VJ e claim:

l. In a tensioning frame for fabric to be embroidered and the like, a rigid inner frame part and an outer frame part consisting of a plurality of separate side members connected together by means of springs, the two frame parts being held together by means of their opposite sides beveled in the form of steps and Working into each other.

2. In a tensioning frame for fabric to be,

embroidered and the like, a rigid inner frame part, an outer frame part consisting of a plurality of separate side members connected together by means of springs and means to swing at least one of these separate side members out of the plane of the frame, when the two frame parts held together by means of their opposite Vsides beveled in the form of steps and working into each other have to be disconnected.

3. In a tensioning frame for fabric to be A embroidered and the like," a Vrigid inner frame part and an outer frame part consisting of four separate side members connected together by means of plate springs, of which at least one is pivotally connected to Vopposite sides of the outer frame part, so that the side of this outer frame part situated be'-v tween said two rst mentioned opposite sides may be swung out-of the plane of the frame when the inner and outer frame parts held together by means of their opposite sides beveled in the form of steps and working into each other have to be disconnected.

4. In a tensioning frame for fabric to be embroidered and the like, a rigid inner frame part and an outer frame part consisting of a plurality of separate side members connected together by means 'of springs, at least one of these springs forming at the same time one of the separate side members of the outer frame Vpart and being pivotally connected to vopposite sides of this outer frame part, so that it is capablerof being swung out of the frame plane when the inner and the outer frame parts held together by means of their opposite sides beveled in the forms of steps and working into each other have to be disconnected.

. In testimony that we claim the foregoing as our invention, we have signed our names in presence of two subscribing witnesses.
